How is alien dna introduced in a plant cell

Dear student,

Alien DNA can be introduced to plant cell by biolistic method (Also called as gene gun method)

A gene gun or a biolistic particle delivery system, originally designed for plant transformation, is a device for delivering exogenous DNA to cells. The payload is an elemental particle of a heavy metal coated with DNA. This technique is often simply referred to as biolistics. This device is able to transform almost any type of cell, including plants, and is not limited to transformation of the nucleus; it can also transform organelles, including plastids
